配置redis伪集群

1 配置redis.conf文件

Redis.conf

include /usr/yyl/redis/redis-5.0.14/redis.conf

port 7001

pidfile "/var/run/redis_7001.pid"

dbfilename "dump_7001.rdb"

dir "/usr/myredis/7001"

logfile "/usr/myredis/7001/redis_err_7001.log"

bind 0.0.0.0

protected-mode no

daemonize yes

#日志这些文件名是根据自己的文件位置修改

复制6份再修改一下

复制6个redis.conf文件到/myredis目录下

2启动节点

7001 7002 7003 7004 7005 7006

把这6个节点(6台服务器)的命令写在脚本里启动

#!/bin/bash

/usr/local/bin/redis-server /usr/myredis/7001/redis.conf

/usr/local/bin/redis-server /usr/myredis/7002/redis.conf

/usr/local/bin/redis-server /usr/myredis/7003/redis.conf

/usr/local/bin/redis-server /usr/myredis/7004/redis.conf

/usr/local/bin/redis-server /usr/myredis/7005/redis.conf

/usr/local/bin/redis-server /usr/myredis/7006/redis.conf

3配置主从节点

/usr/local/bin/redis-cli --cluster create 192.168.74.79:7001 192.168.74.79:7002 192.168.74.79:7003 192.168.74.79:7004 192.168.74.79:7005 192.168.74.79:7006 --cluster-replicas 1

前三个主,后三个从

4检查节点的信息

 /usr/local/bin/redis-cli --cluster check 192.168.74.79:7001

5 关闭节点

可写脚本文件,启动全部

/myredis/stop.sh

#!/bin/bash
str="全部关闭完成!"
/usr/local/bin/redis-cli -h 192.168.74.79 -p 7001 shutdown
/usr/local/bin/redis-cli -h 192.168.74.79 -p 7002 shutdown
/usr/local/bin/redis-cli -h 192.168.74.79 -p 7003 shutdown
/usr/local/bin/redis-cli -h 192.168.74.79 -p 7004 shutdown
/usr/local/bin/redis-cli -h 192.168.74.79 -p 7005 shutdown
/usr/local/bin/redis-cli -h 192.168.74.79 -p 7006 shutdown
#/usr/local/bin/redis-cli -h 192.168.74.79 -p 7007 shutdown
echo $str
str1="检查去集群状态"
 /usr/local/bin/redis-cli --cluster check 192.168.74.79:7001
 /usr/local/bin/redis-cli --cluster check 192.168.74.79:7002
 /usr/local/bin/redis-cli --cluster check 192.168.74.79:7003
 /usr/local/bin/redis-cli --cluster check 192.168.74.79:7004
 /usr/local/bin/redis-cli --cluster check 192.168.74.79:7005
 /usr/local/bin/redis-cli --cluster check 192.168.74.79:7006
 echo $str1

关闭客户端

/usr/local/bin/redis-cli -c -h 192.168.74.79 -p 7001 shutdown

6 新增一个主从节点

1 修改配置文件并启动

启动主从接点 7007 7008
/usr/local/bin/redis-server /myredis/redis7-8.conf

2新增节点

新节点 集群中的节点(前面的IP加端口号是要添加的redis节点，后面的IP和端口号是集群中的任意一个节点。)

/usr/local/bin/redis-cli  --cluster add-node 192.168.74.79:7007 192.168.74.79:7002  --cluster-slave  --cluster-master-id  bdd6c096fb9f5c39891464fb0e827a80e82a2d81

2 分配插槽

/usr/local/bin/redis-cli --cluster reshard 192.168.74.79:7002

3删除节点,删除子节点

/usr/local/bin/redis-cli --cluster del-node 192.168.74.79:7008 ab91e023347e7155069f9cf04ebd574e4ba09417

4删除子节点

1 把插槽还回去,清空主节点

/usr/local/bin/redis-cli --cluster reshard 192.168.74.79:7002

2删除主节点

/usr/local/bin/redis-cli --cluster del-node 192.168.74.79:7008 ab91e023347e7155069f9cf04ebd574e4ba09417
